BUNSEN BURNER.

Application led December 1906.

To all whom it 'may concern.:

Be it known that I, PHILIPP voN VOUWER MANS, of Vienna, Austria-Hungary, a subject of the Emperor of Austria-Hungary, and whose posteoflice address is No. 33 Alserbach strasse, Vienna, Austria-Hungary, have invented a new and useful Improved Bunsen Burner, of which the following is a specification.

The invention relates to improvements in connection with the Bunsen burner described in the applicant/s prior application for United, States Lettersy Patent Serial No. 376,221, filed May 10, 1906, and it hasforits object to increase the effect of the same as much as possible. In order to do this, yit has `been found necessaryT in the first place to give the distributing grate or distributer such a shape that it will offer the largest free section with the least resistance to the entering gas g secondly, to make the size of the holes in the cap of the burner to correspond with the pressure of the gas.

The largest free section available with the least resistance to the entering gas is obtained by making the distributerwcontaining the small channels-conical or A shaped, or by simply arranging the same at an ineline, at the same time sharpening the channel walls, which must be kept as thin as possible, on their lower ends, so that they will not offer resistance to the entering gas, but rather tend to cut the current.

IVith regard to the burner cap, it has been found that in case of high pressure a better result is obtained if the holes are limited to two or three outer rows, the center part being a blank. In case of low pressure it is, however, preferable to perforate the center portion as well and make the holes of the cen ter part of a greater or of the same diameter as the holes of the outer rows, as required. At the same time it is advantageous to make the cap smaller in diameter.

In the accompanying drawings Figure 1 is a vertical section through a burner the distributing grating in the head of which is constructed in the shape of a double sloping roof, and Fig. 2 is a vertical section through a burner the distributing grating in the head of which is arranged at an incline, Fig. 3 is a plan of a cap adapted for high gas pressure, and Fig. 4 is a plan of a cap adapted for Specification of Letters Patent.

,' low gas pressure. -Fig. 5 is a vertical section i showing on a larger' scale the enlarged upper portion of the mixing tube, and the distributing grating therein, Fig. 6 is a horizontal section on the line 6 6, Fig. 5, looking upward and showing a bottoni view of the distributing grating.

In all these figures identical letters of refe erence are used to indicate corresponding parts.

A is the gas nozzle, B is the mixing tube the enlarged upper portion of which constitutes the burner head being provided with a distributing grating a, and C are the airinlets.

The head of the burner shown in Fig. 1 is provided with a distributing grating or distributer a, the lower edges l) of the walls c of which are beveled at both sides so as to present cutting-edges to the current of gas and air. In this instance the distributer is constructed in the shape of a double sloping roof.

In Fig. 2 the distributer e is constructed in the shape of a shed-roof.

The burner Fig. 1 is provided with a cap d adapted for high gas-pressure. As will be seen from the plan shownin Fig. 3 this high gas-pressure cap has two circumferential rows of holes g, the holes of the inner row being of smaller width than those of the outer row ,L the center portionf of the cap is entirely without holes.

The burner Fig. 2 is provided with a cap e adapted for low gas-pressure. As shown in the plan Fig. 4 the center-portion of this low gas-pressure cap is perforated with holes 7L having a slightly smaller diameter than the holes g of the outer row.

That I claim, and desire to secure by Letters Patent of the United States, is:

l. In a Bunsen burner, the combination with a gas-nozzle and a mixing tube having air-inlets in its lower portion, of a distributing grating in the burner head having parallel top and hase planes at an angle to the vertical axis of the mixing tube, the passage walls in said rgrating being vertical to the horizontal plane of the mixing tube, and a cap provided with inner and outer rows of holes, the holes of the inner rows being smaller in diameter than those of the outer row, substantially as set forth.

2. In a Bunsen burner,l the combination with a gas-nozzle and a mixing tube having air inlets in its lower portion; of a distributing grating in said mixing tube having parallel base and top planes oblique to the vertical axis of the mixing tube and constructed with passage walls vertical to the horizontal plane of the tube7 the bottom edges of said walls being beveled to form cutting edges, and a cap provided with inner and outer rows of holes, the holes of the inner rows being smaller in diameter than those of the outer row7 substantially as set forth.

3. In a Bunsen burner, the combination with a gas nozzle and a mixing tube having air inlets in its lower portion; of a distributing grating constructed in the shape of a double sloping roof having walls vertical to the horizontal plane and with lower edges beveled to form cutting edges; and a cap provided with rows of holes the holes of the inner rows being smaller lin diameter than those of the outer rows, substantially as set forth.

4. In a Bunsen burner, the combination with a gas nozzle and a mixing tube having air inlets in its lower portion; of a distributing grating Constructed in the shape of a double sloping roof and having vertical walls whose lower edges are beveled to form outting edges; and a cap provided with circumferential rows of holes the holes of the inner row or rows being of smaller diameter than those of the outer row, substantially as set forth.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
